we generate entire functions as trees. We only want the pushdecl
code that sets DECL_CONTEXT. Each front end sets DECL_CONTEXT
slightly differently though, so we may need new callbacks to the
front-ends to do this right. For now, we just use the code from the
C front end and hope that is sufficient. Alternatively, we could
